Review on Enhanced Barcode Connectivity for Zebra Receipts by Jarrett Love

had the previous generation for 5 years and loved it. This one is even better than the previous one with a better driver, speed, quieter, more robust etc. Bought 2 more after getting a good taste of the GK420d. It is compatible with UPS, Stamps.com, Worldship, Windows 10, Windows 8, Windows 8 Pro, Windows 7 without any problems so far. I'll update the review if anything else comes up.
